The World of Hex Maps
One of the things Open Innovations has become known for is our hex maps or, more correctly, hex cartograms. Hex cartograms are a very useful visualisation technique when the geographies being visualised should be treated equally. For instance, a standard geographic election map of the UK over-emphasises the winners of rural areas because they are much bigger, geographically, even though they are the same size electorally. In this case a hex map would give a more accurate overall impression of the result although at the expense of accurate geography.
Below you can find some example hex visualisations, blog posts we've written, existing hex layouts, and useful hex map tools.

To help create and reuse hex layouts we defined the HexJSON format. Here are some hex layouts that we and others have designed:
NHS Primary Care Networks (2022)
NHS Integrated Care Boards (2022)
UK Wards (2022)
This is a work-in-progress.
UK Upper Tier Local Authorities
UK Local Authority Districts (2021)
UK Local Authority Districts (2020)
UK Local Authority Districts (2019)
By the House of Commons Library
Wales Senedd Electoral Regions
Wales Senedd Constituencies
US Congressional Districts
Yorkshire Water Defined Areas
Whether you want to create a new layout in HexJSON or show some data in a hex layout, we've got tools to help.
